Gradients: gradient table (optional if dMRI is DICOM).MRtrix format supported: file must have '.b' extension and be labeled as 'gradient_table'.FSL format supported: files must have '.bvec' and '.bval' extensions and be labeled 'bvec' and 'bval'.

Preferred DICOM to NIfTI conversion tool (drop-down selection)The selected tool will be tried first to convert DICOM to NIfTI. If the conversion fails, the other options will be tried sequentially until a successful conversion.

Gradient, Motion, Eddy & Distortion correctionThe following information about the sequence protocol is required for optimal pre-processing Echo Spacing (s): The time between echoes in an echo planar image (EPI).Echo Factor: also called Echo Train Length (ETL), the number of echoes acquired in a single repetition time (TR),Acceleration factor: the number of EPI lines acquired in parallel.Echo Difference (s): (only needed if GFMs are provided), the difference in Echo Time (ET) between GFM acquisitions. Default value is typical for SIEMENS scanners.
